I thought you might be interested in a project we have been working on at the Department of Computer Science, University of Tromso, Norway. We have built a system that makes it possible to navigate gigapixel-scale images on a 22 megapixel display wall.
Typically, when you view a gigapixel image, you do that through a browser plugin that not only confines the view to the size of your browser window, but also suffers from fairly low performance. Loading times are long, which makes exploring the image an exercise in waiting. You never fully get to appreciate the scale and level of detail in the image.
Our system is built from 28 projectors and about 30 computers that work together to create a seamless, high-resolution, wall-sized display. Another 16 cameras and 8 computers enable touch-free, multi-point interaction with the wall. We recently used this setup to visualize a 13.3 gigapixel image of Tromso with very good performance. Now, rather than looking at gigapixel-scale images in a tiny browser window, we are able to navigate such images on a roughly 6x3 meter (19.5x9 ft) surface while maintaining good dpi and dramatically improve the performance of existing browser-based solutions.
Granted, not everyone has a display wall at their disposal but...
